The old Rayman games have their charm, I played a few of them back in the day but didn't think they were that special. Origins and Legends were big reboots and brought the gameplay right up to date though. Definitely on par with some of the best Mario games IMO.

Plus the art style is gorgeous

I read about Legends having coop. Is this sort of what New Super Mario Bros. Wii brought to the table? If so, awesome!
